Mainframe cost is heavily dependent on the real CPU load through the IBM mechanism for charging Software by the 4 hours rolling average. By precisely monitoring various loads (as detecting rapidly abnormal CPU peaks, optimizing Disk I/O and using new features as Large pages), EPV provides a toolset to reduce the CPU load (and hence the IBM Software charging) while better using it.

Mainframe Optimization with Modern SystemsModern Systems
Our Mainframe Optimization services are for customers that want to keep mainframe apps- and extend their capabilities to support new business requirements.
Liberate Nonrelational Data Without A Migration - Mainframe DataShare
Operational and transactional data to support big data architecture and reporting is often trapped in nonrelational databases that don’t integrate with modern data warehouses. Empower true business intelligence by integrating nonrelational databases still in the legacy environment with relational data warehouses- without disturbing IT or end users.
Reduce MIPS Costs Up To 40% Without Impacting End Users - Batch Off The Mainframe
Mainframe optimization through offloading workloads to reduce MIPS can be transparent to end users when planned and executed with adequate computing resources. Batch Off Mainframe service leverages off-mainframe processing power to reduce mainframe MIPS and overall cost-of-ownership.
Extend Business Value of COBOL Applications - Mainframe Field Expansion
Over time, data standards have been implemented and mixed across applications and databases- making change of any kind risky. Our solution reaches across the all lines of code that comprise your applications, both online and batch- and applies controlled, standardized change.
From time to time, there is a need to modify information systems due to changes in legislation (like SOX), standards, currency change (like the euro), and more. These types of changes have a substantial impact on many components of an information system and therefore contain a high risk factor.
The results from Syncsort’s annual State of the Mainframe Survey are in! The importance of mainframe data is rising as a critical component of enterprise-wide strategies that leverage modern data architectures for Big Data analytics and security and compliance. Join us for a live webcast and Q&A as we take you through an in-depth look at the survey results and the four trends to watch for in 2017.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Introduction
Reduce mainframe cost while
improving application performance is
still one of the most important goals
of companies running z/OS
applications
In many situations needed actions
require both a technical analysis and
a management decision
In this presentation, starting from
real life examples, we will focus on
what are the most common tuning
opportunities we found at many sites

4. Agenda
1. Who’s Using My CPU?
2. The Best I/O is no I/O
3. Large Memory Pages
4. WLC Checks for Managers

6. Who’s Using My CPU?
6
This is an example of the abnormal
behaviour of a monitoring tool
It normally uses few MIPS but for some
reasons on Saturday morning started to
loop using almost a full CPU
Customer technical team tried to restart
the STC; it worked; in the mean time
they asked for a correction from the ISV
7. 7
Two heavy TSO users in the peak hours
Customer created a Type3 WLM
Resource Group with a maximum limit
of 30% including the ALLTSO service
class
A management decision may be needed
Who’s Using My CPU?
9. Application tuning requires a joint
effort between technical and
developent teams
Most of the times management
decision and commitment is needed
9
Who’s Using My CPU?
11. Accessing data in memory provides better
performance and less CPU usage
Many Data In Memory possibilities available
in z/OS; most of them since many years
Because of current disk performance most
sites don’t care about the number of I/Os
they do
To understand if the system I/O load is
excessive we suggest to use the IOC index
(calculated dividing the AVERAGE DISK I/O
RATE by AVERAGE MIPS USED)
Values higher than 3 should be investigated

1000 I/O per second =
1000 / 50 = 20 MIPS
Recent IBM study (Feb 2015) estimated
35 CPU microseconds (on a 2827-712)
per DB2 synchronous I/O
1000 I/O per second =
0,035 * 14166 / 12 = 41 MIPS

20. Virtual memory above 2 GB can only
be allocated by using memory objects
A memory object is a contiguous range
of virtual addresses that is allocated in
units of megabytes on a megabyte
boundary
Memory objects can be written to 4K,
1MB and 2GB pages (available since
zEC12)
1MB and 2GB pages are called large
memory pages

In addition to Segment
and Page tables:
• Region 3 tables to
map 2048 segment
tables (up to 4 TB)
• Region 2 tables to
map 2048 Region 3
tables (up to 8 PB)
• Region 1 tables to

23. As a general rule large pages may provide
performance value to long-running
memory access-intensive applications
First large memory pages exploiters:
the z/OS nucleus (since z/OS 1.12)
DB2 buffer pools (since V10) when the
PGFIX=YES parameter is specified
JVM can use large memory pages (both for
code-cache and heap) by specifying the –
Xlp option; more recent JVM versions will
automatically use large memory pages if
they are available

26. WLC Checks for Managers
Customers have the primary responsibility for preventing
uncontrolled loops, operator errors, or unwanted
utilization spikes. However, IBM understands that,
occasionally, situations that could not be prevented
(especially situations related to disaster recovery) might
cause exceptional utilization values. In these situations,
IBM does not normally expect customers to pay for the
increased utilization associated with the unusual
situation. Use your best judgement to determine if an
unusual situation has occurred. IBM does not publish a
list of unusual situations because, by their nature, they
will be unpredictable.
From the “Using the Sub-Capacity Reporting Tool”
manual.

28. Not a “beautiful” day ?
Bad news
At this customer site Saturday and
Sunday are not business days so a
such high value on Sunday has to be
considered abnormal
In this case it was caused by a long,
recovery activity needed to fix a data
corruption issue following the
migration to new storage processors
which happened on the previous day

contributions, it appeared clear that
the peak was due to something running
inside the SYS2 system

33. The system you don’t expect
A more detailed ZNET workload analysis
showed a correspondent CPU increase of the
session manager address space
The new version of the session manager
caused such a big increase (about 40 MSUs).
In this case most of these MSUs were
recovered thanks to some PTFs
Being able to measure and report this issue
gave the customer the possibility of
discussing the October and November
monthly bills with IBM in order to reduce
them
